Immutep Reports Improving Results from INSIGHT-004 Trial
41.7% of patients showed a Partial Response to the combination therapy of eftilagimod alpha and avelumab (previously 33%)
Encouraging early anti-tumour activity signals in a variety of cancer indications not typically sensitive to immune checkpoint inhibitor (ICI) therapyCombination of eftilagimod alpha and avelumab continues to be safe and well tolerated SYDNEY, Australia, Sept. 18, 2020 (GLOBE NEWSWIRE) — Immutep Limited (ASX: IMM; NASDAQ: IMMP) is pleased to report further interim data from its ongoing INSIGHT-004 Phase I clinical trial. The data were presented at the ESMO Virtual Congress 2020 on 17 September 2020, CEST (poster ID number 1032P) by trial investigator at Institute of Clinical Cancer Research, Krankenhaus Nordwest (IKF), PD Dr. Thorsten Götze.INSIGHT-004 is evaluating the combination of Immutep’s lead product candidate, eftilagimod alpha (“IMP321” or “efti”) with avelumab (Bavenico), a human anti-PD-L1 antibody, in 12 patients with different solid tumours, primarily gastrointestinal. It is being conducted under Immutep’s collaboration with Merck KGaA, Darmstadt, Germany, and Pfizer Inc., which are co-developing and co-commercialising avelumab. INSIGHT-004 is the fourth arm (Stratum D) of the investigator-initiated INSIGHT trial which is conducted by IKF in Frankfurt, Germany.Prof Salah-Eddin Al-Batran, INSIGHT-004 trial investigator and Director of IKF said: “It is encouraging to see the range of patients with different solid cancers that are responding to the combination of efti and avelumab, including PD-L1-negative cervical cancer, squamous anal cell carcinoma and mesothelioma. These tumours are not typically responsive to immune checkpoint therapy and warrant further investigation.”Results Summary (data cut off 12 June 2020)41.7% of patients (5 / 12) showed a partial response (PR) to the combination therapy according to RECIST 1.1. Previously 33% showed a PR (June 2020).Encouraging durable deep responses in PD-L1 negative cancer.*Includes 2 patients with clinical progression
**Response assessment not yet performedSafety
Interim results from INSIGHT-004 show that the combination of efti and avelumab is well tolerated with no dose limiting toxicities, building on efti’s strong safety profile to date.IKF INSIGHT Trial Poster
IKF also presented data from the broader INSIGHT trial at ESMO showing that intratumoral and intraperitoneal administration of efti up to 30 mg displayed signals of clinical and cytokine responses.

INSIGHT-004 is the fourth arm of the investigator-initiated INSIGHT trial which is being conducted by the Institute of Clinical Cancer Research IKF at Krankenhaus Nordwest in Frankfurt. It is being conducted under Immutep’s collaboration with Merck KGaA, Darmstadt, Germany, and Pfizer Inc., and is evaluating the safety, tolerability and recommended Phase II dose of efti when given in combination with avelumab. It is the first combination trial of an approved and marketed anti-PD-L1 drug and efti.Patients in cohort 1 receive 6mg doses of efti every two weeks with the standard dose of avelumab (800mg every two weeks), while patients in cohort 2 receive a higher dose of efti, 30mg, with avelumab.Further information can be found on the Company’s website www.immutep.com or by contacting:Australian Investors/Media:
